RAIL ANCHOR AND TIE PLATE Filed NOV. 30, 1936 Patented May 10, 1938 AUNITED sTATEs rATENT OFFICE 2 claims. (c1. 23a- 364) The inventionrelates to tie plates and more especially to combined rail anchors andtie plates.

One of the numerous troubles confronting rail roads is the preventionofthe runningor creeping of the railsof a track whichcauses too muchexpansion in some places and joints becoming too tight in other places,even becoming so tight that a rail Will .buckle in hot weather throwingthe track out of alignment and thus making it dangerous for the passageof trains and frequently becoming tight enough on bridges to throw theframework out of line.

The primary object of the present invention is the provision of a plateof this character, Wherein the difiiculties above expressed will berelieved in that the rails of a track will be successfully anchoredagainst running in either direction or creeping and thereby eliminatekinks in the rails where the spikes are loose and thus assuringalignment irrespective of the size of the rails of the track.

Another object of the invention is the provision of a plate of thischaracter, wherein the same will be firmly held in place and the railanchored to avoid the creeping of the latter and also the shifting ofthe plate when upon the tie thereby giving greater life to the track andavoiding liability of the spreading of the rails and accidents incidentthereto.

A further object of the invention is the provision of a plate of thischaracter, which is simple in construction, thoroughly reliable andeffective in its operation, durableand inexpensive to manufacture andinstall.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the prefered embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary top plan view of a track rail and cross tieshowing the combined rail anchor and tie plate constructed in accordancewith the invention applied.

, Figure 2 is a sectional view on the line 2-2 of Figure 1 looking inthe direction of the arrows.

Figure 3 is a perspective view of the tie plate.

Figure 4 is a perspective View of one of the wedge keys for use with thetie plate.

Similar reference characters indicate corresponding parts throughout theseveral Views in the drawing.

Referring to the drawing in detail, A designates generally a portion .ofa track rail and B .a portion of a tie, these bein-g conventional and asusual the said rail fis made. fast to the tie by spikes :I which in thisinstance ,are in association with a combined anchor and tie plateconstituting the present invention and hereinafter fully described.

The plate constituting the present invention comprises a body section IIhaving a flat bottom face I2 while intermediate the opposite ends of 10this plate at the top thereof is a rail base bearing I3 while upstandingfrom this body section at opposite sides of the bearing I3 riseshoulders I 4 and I5, respectively.

Formed between the bearing I3 and the shoul- 15 der I5 is a channel-likekeyway I6 which has its side walls I'I parallel with each other anduniformly spaced with relation to one another throughout the extentthereof. This keyway opens through opposite edges of the body I I whileprovided in the said body and intersecting the shoulder I4 and thekeyway I6 are spike holes I8 and I 9, respectively, for accommodatingthe spikes I 0 in fastening the plate body II superimposed upon the tieB. These spikes when 2 driven through the holes I8 and I9 into the tie Bengage with the base 20 of the rail A for the fastening of said rail inplace and attached to the tie B, the base 20 of the rail being seatedupon the bearing I3 of the plate body II as is clearly 30 shown inFigure 2 of the drawing.

Insertable in the keyway I 6 through opposite ends thereof are reverselyarranged wedge shaped keys 2|, these having outer driving heads 22 andeach is formed with a reduced ledge or 35 rib 23 at one longer side edgethereof to underlie the base 20 of the rail A so that this base will`have contact with the key at the shouldered side 24 thereof when driveninto the way I6 thus making secure the rail on the plate body II. Thisrail at the edge opposite to that engaged by the keys 2l will abut theshoulder I4, these keys 2l become wedged in the keyway I 6 when driventhereinto by wedging action against the shoulder I5 and the base 20 ofthe rail next 45 thereto. The ledge 23 of the keys 2| prevents theworking upwardly of the said keys out of the keyway I6 in the usethereof.

Each key 2I has formed therein a notch 25 opening through the otherlonger edge of the key opposite the ledge 23 and this notch accommodatesa spike Il! passed through the hole or opening I9 intersecting thekeyway I6 and thus such key will be held secure and fast by the saidspike.

The plate body II with the use of the keys 2I 55 will anchor the rail Aand the manner of attachment of the plate body I l to the tie B avoidsany possible creeping of the said rail and the kinking of the rail withthe result that the said rails will be out of alignment or spread fromeach other. By the use of the two keys 2| with the plate body l I therail can not creep in either direction longitudinally of the trackage.

Each key 2l from the opening 25 to the smaller end thereof may be of athickness corresponding to the thickness of the ledge 23 whereas thesaid key at the other end portion or at the opposite side of the opening25 may be materially thickened with respect to the ledge 23.

What is claimed is:

1. A combined anchor and tie plate comprising a body having an insetrail bearing in its top face, said body at one side of the longitudinalcenter line of said bearing having a longitudinally extending grooveprovided With vertical side walls parallel with each other and to thelongitudinal center line of said bearing, the outermost side wall of thegroove being extended upwardly for effecting a shoulder, spike-likeWedging keys inserted reversely to .each other in opposite ends of thegroove for engaging a rail base and the edge of the outermost side Wallof the groove,l and spikes passed through the keys and plate body nextto the inner ends of said keys and having heads overhanging the railbase for the fastening thereof upon the bearing, said keys and platebody having openings for said spikes adapted to register when the keysare in their driven positions.

2. A combined anchor and tie plate comprising a body having an insetrail bearing in its top face, said body at one side of the longitudinalcenter line of said bearing having a longitudinally extending grooveprovided with vertical side Walls parallel with each other and to thelongitudinal center line of said bearing, the outermost side `Wall ofthe groove being extended upwardly for effecting a shoulder, spike-likewedging keys inserted reversely to each other in opposite ends of thegroove for engaging a rail base and the edge of the outermost side Wallof the groove, spikes passed through the keys and plate body next to theinner ends of said keys and having heads overhanging the rail base forthe fastening thereof upon the bearing, said keys and plate body havingopenings for said spikes adapted to register when the keys are in theirdriven positions, and shallow flanges formed at the inner sides of thewedging keys for underlying the rail base.
